A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft.
A composite photograph showing the Bell X-5’s variable-sweep wing. The Bell X-5 was the first aircraft capable of changing the sweep of its wings in flight.It was inspired by the untested wartime P.1101 design of the German Messerschmitt company.
The aircraft is predominantly made from wood and covered in doped Ceconite. The wing leading edge is made from poplar plywood and supported by nose ribs made from marine-grade plywood. The wing spar cap strips and tail ribs are fashioned from spruce. The tailboom is an aluminium tube. Its wing is cantilevered and tapered from wing root to wing ...
Spanwise airflow over a forward-swept wing is the reverse of flow over a conventional swept wing. Air flowing over any swept wing tends to move spanwise towards the aftmost end of the wing. On a rearward-swept wing this is outwards towards the tip, while on a forward-swept wing it is inwards towards the root.

The first variable-sweep aircraft from Dassault emerged as the single-engined, two-seat Mirage G fighter in 1967, essentially a swing wing version of the Mirage F2.The wings were swept at 22 degrees when fully forward and 70 degrees when fully aft and featured full-span double-slotted trailing edge flaps and two-position leading edge flaps.
A variable-sweep wing (swing-wing) is a type of pivoted wing that takes advantage of the aerodynamics of a swept wing at high speeds while swinging straight to avoiding the drawbacks of such a design at lower speeds.
[1] [7] (The first known oblique wing design was the Blohm & Voss P.202, proposed by Richard Vogt in 1942. [8]) Jones's wind tunnel studies indicated that such a wing design on a supersonic transport might achieve twice the fuel economy of an aircraft with conventional wings.
